add build.config's for upstream LTS branches

As we cannot store build.config files (used for build/ within
the upstream repositories (they are plain upstream mirrors), provide a
configuration hierarchy here and refer to them from the kernel/manifest
for the branch.

The build.config files can be used to build upstream kernel branches
with build/ after acquiring sources (and toolchain!) with repo.

The background behind this change is to ensure stable toolchains and
configurations when building kernels. That is useful for ABI-checked
